...of Slow People
1. Slow people always walk side by side, even if they don't know each
other.
2. They drive side by side, too. If they can't find another slow
driver to pair up with, they drive in the fast lane.
3. Slow walkers never look back. When they drive, they never look in
their rear view mirrors, either.
4. Slow people drift sideways so they'll block the path of anyone
trying to pass them. If two people or vehicles are trying to get
around them at the same time, they drift into the path of the one that
is moving at the highest speed.
5. Follow behind a slow person in the grocery store and you'll wind up
with soggy ice cream every time.
